Learning Objective
I can find the area of composite figures by breaking them into rectangles and triangles.
- 1
To find the area of a composite figure, separate the figure into simpler shapes like rectangles and triangles.
- 2
The formula for the area of a triangle is base x height ÷ 2, and the formula for the area of a rectangle is length x width.
- 3
After finding the area of each individual shape, add the areas together to find the total area of the composite figure.
